To all. whom it may concern: X

'Methods of Weaving Pile Fabrics, of which the following is a specification. My invention relates to weaving pile fabrics, and particularly to an improved method of weaving ile fabrics of the class in which the pile tu t yarn is'separate from the binder and stuifer warps, and the weft threads, and is inserted in a series of rows between the binder and stuft'er warps, to form a cut pile surface or face on the fabric, as moquettecarpets, and Axminster carpets.

The object of my invention is'to improve upon the ordinary method of weaving pile fabrics of the class above referred to.

In the ordinary method of weaving pile fabrics of the class above referred to, a' series of pile tufts are inserted between the warps, and a weft thread is inserted into the shed, andthen the free ends of the pile tufts are moved upwardly between the warps, from the underside of the weft thread, by a comb, and pass up on the opposite side of the weft thread, and partially encircle the weft thread, which acts to hold the tufts in the fabric, after the weft threads are beaten up. In my improved method of weaving pile fabrics of the classreferred to, instead of passing the ile tufts around the weft or :filling 'threa a, they are passed around a stu'ifer' 'warp, or one of the binder warps, that is around the threads which extendv in the direction of the length of the fabric.

In carrying out my improved method of weaving pile fabrics of the class referred to, I preferably use a reed having the dents thereof so formed or shiafped, that in weaving the fabric, certain stu er -or warp threads are moved to one side at the proper time, to

allow the tube frame to carry the ends of the pile tufts down between the warps, and the 3 ends of the pile tufts are then moved up between the warp threads, by the operation of the comb, to cause the pile tufts to be carried around and partially encircle a stuffer, or one of thebinder warp threads.

- Each series of pile tufts extend in the direction of the length of the fabric, and partially encircle, preferably, a single-stutter, or binder warp thread- I have shown in the drawings, on 'an exaggerated scale, diagrammatieviews to illustrate my improved method of weaving pile fabrics of the class referred to, and mechanism which may be used for carrying out my improved method, sufficient to enable those skilled in the art to understand the construction and operation of my improvements.

Referring. to the drawings -Figure 1 is a diagrammatic view showing the shed formed by the first position of the harnesses,

and the free end of a pile tuft inserted. Fig. 2 shows the shed. formed by the second position of 'theharnesses, anda pile tuft passed upwardly around a stufier warp. Fig. 3 shows the shed formed by the third position of the harnesses, and a pile tuft cut oil. Fig. 4 shows the shed formed by the fourth position of the harnesses. Fig. 5

is a section, on line 5, 5,Fig. 1 looking in the direction of arrow a, same fi 6 corresponds to Fig. 1, but shows a modified construction of the reed dents, to cause a pile tuft to pass around a binder warp, instead of a stufi'er warp. Fig. 7 corresponds to Fig. 2, but shows. a pile tuft passed around a binder warp the upper plane of the shed. Fig. 8 corresponds to Fig. 3, but shows a pile tuft passed around a binder warp in the upper plane of the shed- Fig. 9 corresponds to F ig. 4, but

shows a pile tuft passed around a binder warp in the upper plane of the shed, and,

Fig. 10 is a section, on line 10, 10, Fig. 6,

looking in the direction of arrow 22, same figure. 1

- In the accompanying drawings, 1 is the lay beam, having the dents 2 of the reed mounted thereon.

3 is a bar, which carries the comb 4 in the usual way. A

5 are the tuft yarn carriers or tubes, which guide a pile tuft yarn 6 from the spool, not shown.

. 7 is a stuflei' warp, and 8 and 9 are binder warps, and 10 is a double filling or weft thread.

I will first gure. Flg.

describe. my improved method of weaving pile fabrics in which the pile tufts arepassed around the stufl'er warps, as shown in Figs. 1 to 5, inclusive.

The dents 20f the reed are formed with a double offset 2, on one side, which causes the stuffer warp 7 to be moved sidewise, as shown at the left in Fig. 5. The stutter warps are moved to the left by the offset 2 in the dents 2 of the reed, and leave a space between a stutter warp 7 and the binder warps 8, and 9, see Fig. 5, which is suflicient for the free end of the pile tuft yarn 6 to be inserted between the stuifer 7, and binder warps 8 and 9, as shown in Fig. 1, in which figure the lay l, and reed comprising the dents 2, have been moved halfway toward the fell of the fabric, and remain in this position to allow thetube 5 to put the end of the pile tuft yarn 6 down between a stufi'er warp 7, and the binder warps 8 and 9.

By the movement of the harnesses, the position of the stufi'er war 7, and binder warps 8 and 9 are change to the position shown in Fig. 2, and the operation of the comb 4: moves the free end of the pile tuft yarn 6 from below the stufi'er warp 7, and around the stufl'er warp 7, and up between the stufl'er warp 7, and the binder warps 8 and 9. The continued operation of the loom will sever the tuft yarn 6, as shown in Fig. 3, and withdraw the tuft yarn carrier 5, leaving the pile tuft 6 around the stuffer warp the shed having been changed by the movement of the harnesses, as shown in Fig. 3, to carry the binder warp 8 into the lower plane of the shed for the insertion of a double filling 10. The filling 10 is then beaten up by the reed to the fell of the fabric, as shown. The next movement of the harnesses changes the shed, as shown in Fig. 4:, when the stuifer warp 7 is brought to the lower plane of the shed, and another double filling 10 is inserted in the upper plane of the shed and beaten up. These operations are repeated throughout the length of the fabric.

I will now describe my improved method of weaving pile fabrics in which thepile tuft is passed around a binder warp instead of astutter warp, see Figs. 6 to 10. The dents 2 of the reed have m this instance a single oifset at 2", which causes the warps in their downward movement, to be moved sidewise of the warps which remain in the upper plane of the shed, as shown at the left in Fig. 10, leaving a space between the binder warp 8 in the upper plane of the shed, and a stufl'er warp 7 and a binder warp 9 in the lower plane of the shed, sufficient for the end of the pile tuft yarn 6 to be inserted, as shown in Figs. 6 and 10. The position of the warps are then changed to the position shown in Fig. 7, and the operation of the comb 4 passes the free end of the pile tuft yarn 6 around the binder warp 8 in the upper plane of the shed of the fabric. The continued operation of the loom will sever the pile tuft yarn 6, and

.withdraw the tuft yarn carrier 5, the movement of the harnesses having changed the shed, as shown in Fig. 8, to carry the binder warp 8 into the lower plane of the shed for a double filling 10 to be inserted. The filling 10 is then beaten up by the reed to the fell of the fabric'for the next movement of the harnesses to change theshed as shown in Fig. 9. The stufler warp '7 is also brought to the lower plane of the shed, and another double filling 10 is inserted in the upper plane of the shed, and beaten up by the lay. The binder warp 9 isnow in the upper plane of the shed, preparatory to the next insertion of the pile tuft yarn 6, to be passed around said binder warp 9, and these operations are repeated throughout the length of the fabric, causing the pile tuft yarn to be passed around the binder warp in the upper plane of the fabric.

In my improved method of weaving pile fabrics the pile tufts are passed around either the stufi'er warps, which extend through the body of the fabric, or around the binder warps which extend in the upper plane of the fabric, and are thus securely attached to the body of the fabric.

It will be understood that any suitable mechanism for carrying out my improved method of weaving pile fabrics may be used. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. An improved method of weaving pile fabrics which have the pile tufts separate from the body of the fabric, and passed around the stufier warps, and which consists in moving the stufi'er warps to one side, to leave a space between the stufier warps and the binder warps, inserting the free ends of the pile tuft yarns between the stuifer warps and the binder warps, changing the shed, moving the free ends of the pile tuft yarns around the stuffer warps, and up between the stufier warps and the binder warps, cutting the pile tuft yarns, changing the shed, inserting a filling in the lower plane of the shed, and beating up said filling, changing the shed again, and 1nserting a filling in the upper plane of the shed, and beating up said filling.

2. An improved method fabrics which have the pile tufts separate from the body of the fabric, and passed around a binder warp, and which consists in moving some of the binder warps to one side, to leave a space between the binder warps in the upper plane of the shed, and the'stufier warps and the binder warps in the lower plane of the shed, inserting the 5 shed, moving the free ends of the 'pile tuft free ends of the pile tuft yarns between the in the lower plane. of the shed, and beating binder warps in the upper plane of the shed, up said filling, changing the shed again, 10 and the stufier warps and the binder warps and inserting a filling in the upper plane of in the lower plane of the shed, changing the the shed, and beating up said filling.
